Caught Mom gets fucked and loves it

My two closest friends and I were playing video games down in the basement after school, which was let out early that day because of a snowstorm. Bill was eighteen, like me, and Harold had just had his eighteenth birthday. We heard my Mom come home but did not stop our playing. About fifteen minutes later we heard the doorbell ring and started up stairs to see who it was. We thought it might be another of our friends. When we got to the top of the stairs we could see that Mom had gotten to it first so we stopped. We were kinda around a corner from the side so we had not been seen but we could see Mom go to the door.

My mother opened the door. There was a man in a UPS uniform but we didn’t see a package it his hands. He stepped inside and shut the door. Mom was standing close in front of him. Then she dropped to her knees and reached out, unhooking his belt, unzipping his fly and pulling his pants and shorts to the floor. His cock stood erect in front of him pointing right at my mother’s face. She reached out and took it in her hand and she put her lips around the head. He put his hand behind her head and shoved himself half way into her mouth. Mom started moving her mouth up and down on his shaft and you could see her cheeks pull in as she sucked. She took her hands away for a minute to unbutton her blouse. She wasn’t wearing a bra and her big D-cup tits were fully exposed. The UPS man reached down and started playing with her tits and rolling her nipples between his fingers while she put her hands behind his ass and pulled him deeper into her mouth. Almost all of what I guessed was seven inches was now going in and out of Mom’s mouth in a rapid fucking motion with them both moving. This went on for about five minutes while we all watched her giving him a blowjob. Finally he threw his head back and groaned loudly and held himself still and buried deeply in her mouth.
